Title: Treshold alarms for processing errors in a multiplex communications system
IPC: G06F11/22
Filed: 1988-08-05
Abstract: A method and apparatus for detecting and analyzing errors in a communications system is described. The method employs expert system techniques to isolate failures to specific field replaceable units and attempts to restore the failing unit to service, if the system will not be adversely affected, by removing it from service, resetting the resource and returning it to service if it passes retesting. The expert system techniques include detailed decision trees designed for each resource in the system. The decision trees also filter extraneous sources of errors from affecting the error analysis results.

Title: Gaiter
IPC: A43B23/06
Filed: 1988-03-04
Abstract: A boot or shoe has a gaiter, the lower end of which 
is permanently affixed by a waterproof join to the boot 
or shoe's outer surface, circumscribing the said boot 
or shoe above the sole. The gaiter has an opening 
extending down from the top, and a fastener, which when 
closed helps to keep the gaiter in an upright position 
on the wearer's leg. A gusset is disposed inwardly of 
the opening and forms a tubular shape when the fastener 
is closed. A pull cord or other closure at the top of 
the gaiter is operable to constrict the gaiter's upper 
periphery around the wearer's leg. This closure inhibits 
the flow of water into the boot or shoe. When not 
required, the gaiter folds down around the ankle of the 
wearer's leg.

IPC: C07C263/04
Filed: 1989-07-25
Abstract: In the preparation of diisocyanates from diamines, urea and alcohols with thermal cracking of the biscarbamate formed, it has hitherto been impossible to utilise the by-products formed in the cracking stage, and thus to arrive at a technically practicable and economical process. It was therefore the object of the invention to search for an appropriate way which avoids the said disadvantages. 
<??>The object was achieved when a cyclic process for the preparation of (cyclo)aliphatic diisocyanates was found wherein, starting from diamines, by-products from the thermal cracking, urea and alcohol, the biscarbamate is produced in the presence of N-unsubstituted carbamates and dialkyl carbonates and with removal of NH3, the subsequent cracking of the biscarbamate is carried out in the liquid phase without solvent, the diisocyanate and alcohol are condensed, the diisocyanate is subjected to a final distillation and a part of the reaction mixture from the cracking with the by-products formed is purged and, after first being reacted with raw alcohol arising, is recycled to the biscarbamate preparation stage.
